Is there any De-fueling?

[RaZe]

I received my chip today! and my big PHP mouth sticker

i am installing it later today.... but i was wondering....

at any psi in boost does the truck start to de-fuel? also how much psi can the turbo handle (not on a daily basis but more of like a once in a while drag or dyno run)???

thanks!

Try to keep it under 25 PSI.

Nothing set in stone, but it's the general consensus. If you can hit 25 PSI, you're good.

well i have hit 26psi stock. the wast gate is unplugged. but im going to plug it back in.

In the higher-hp settings, that won't do anything. Bill commands the wastegate solenoid valve to stay closed anyway and there isn't a pressure signal sent to the actuator.

ok so it will be ok if i leave it unplugged? because the jackass that put my boost gauge in hooked it up to the red waste gate line and the T fitting is broke off and stuck in one side of the red line. so ...ya haha

there is also a torque reduction map for reducing torque when the truck shifts gears under heavy throttle.. I think it defuels to do this. I know zip about automatic trannys but Cody will be able to let ya know if I am correct on how it does it..

ok well if thats true then that makes sense i have no problem with that. i just didnt want any defueling under certain psi of boost. thanks!
